Release 1.6.6, etc...
by Richard B. Kreckel 31 Dec '15

31 Dec '15

Hi! GiNaC release 1.6.6 is out and available. These are the changes: * Fix elusive bug in add::eval(). * Several minor performance enhancements. So far for the master branch... In an attempt to curb down the number of warnings when GiNaC is compiled with a C++11 compiler, I created the c++11 branch. It turns out that the new language revision offers solutions for some of the problems for which awkward workarounds had to be introduced previously. As a result, the code on the c++11 branch has started to diverge from that on the master branch. It is not compatible to C++89 / C++03. I intend to merge the c++11 branch back to the master branch somewhen in 2016 and release that as a new major version. (BTW, GCC 6 is supposed to be released in 2016 and will use C++14 by default.) Until then, it is probably pointless to commit anything than a real bugfix to the master branch (which might then be released as version 1.6.7). Any other patches are very welcome, but they should be based on the c++11 branch, please. Nuff said. Back to hacking... -richard.

Dear Richard, It is nice to see that GiNaC received a serious revision. It also inspires some further contributions: I am attaching two small patches.

MSVC 18
by Jan Rheinländer 17 Dec '15

17 Dec '15

Hi, I successfully compiled GiNaC (and CLN) with MSVC 18.00.31101 (Visual Studio 2013). All the tests passed, but I had to patch two files: check/exam_cra.cpp ginac/polynomial/mod_gcd.cpp Both of these files require #include <algorithm> otherwise there is an error about 'min' not being a member of namespace std.
